Web Relay Controller

The ZADR85DPDTProXR_Web-i Web Relay Controller has built-in web pages in the module that you can access with any device with a browser! Since this is
browser based you can access the pages regardless of the platform. Any browser on Android, IOS or Windows devices can be used on a phone,
tablet or computer to control the relay from anywhere you have an internet connection!

ZADR85DPDTProXR_Web-i The Ideal Choice

The ZADR85DPDTProXR_Web-i Web Relay Controller is extremely easy to work with since the working web pages are already there (in the Ethernet module not a separate
web site). No app or special software required...just a browser! Plug the board into a router using a standard CAT5 cable
and it's assigned an IP address. Access that IP address in any browser and you can control relays without programming or special knowledge.

Web Relay Controller - ProXR

This is a ProXR board meaning that it has the industry leading command set and the board can be expanded to include up to 256 relays.
Adding relays is as easy as adding expansion boards as your needs arise.

Use Any Device with a Browser

Control this Web Relay from anywhere you can get an internet connection and on any device with a web browser. The Web-i interface built into this controller plugs in to a router on your network. This tiny controller has built-in web pages, which give you access to the relays on the board. These are working web pages that are ready to use or you can edit them with your favorite HTML editor.

Connectivity Options

Web-i controllers can be accessed remotely through an Internet connection using any device with an embedded web browser such as a smartphone, tablet, or computer. The Module has firmware built-in that will allow you to access the web pages and that will
send commands to the board.

Web Relay Modules

This board is equipped with a Web-i Module. The Module has custom firmware built-in that will allow you to access the built-in web pages. Those pages will allow you to send commands to the board such as simple on/off commands or complex timing commands. The Web-i communications module also adds an Ethernet interface to the board and will connect to a your router with a standard CAT-5 cable (a Wi-Fi adapter is available - see below). The Web-i module will be powered by the board which will require 12 volts of power that can be hard wired or you can purchase a "wall wart" type Power Supply at checkout. For more information on Web-i interface see Web-i Interface. Lantronix XPort Pro Datasheet

Built-In Working Web Pages

The Web-i Module has built-in working web pages that will let you control the relays and read analog inputs. You can also set passwords, create macros and send ProXR Commands all through pages that are already there! These are working pages that are ready to go as soon as you establish communication to the board but it doesn't stop there. Using a simple ftp program and HTLM editor you can download and modify the pages to fit your needs or company look including adding your logo and company information.

LAN or Internet Control

Control relays from your local internet only when you are connected to your local area network or control from the internet from anywhere outside your network. Once your router is properly configured for port forwarding, users may access the web pages built into the Web-i interface from anywhere in the world just like it were a normal web site. Simply use the Web-i web pages to monitor and control your electronics or customize the pages for your own needs.

Connectivity of Web Relays

Control these relays using the preferred web browser of your smart phone, tablet or computer. There are two main variations on communicating with the relays, Local Control and Global Control.

Local Control

Local control is the easiest way to gain access to your Web Relays. Local Control means your mobile and the Web-i relay controller are both connected on the same network in a local area. For instance, you are at work and your phone and Web-i device are connected to your office network using the same office router (which support Wi-Fi for your phone and Ethernet for the Web Relay controller).

Simply enter the IP address of the Web-i device into the URL bar of your favorite browser. You will have instant access to the web pages built in to the Web-i controller. When connected in this way, you will only have access to the relay controllers as long as your computer or mobile device is in range of your local area network. Users outside the network will not be given access to the controller. Global Control gets around this limitation.

Global Control

Global control means you can control a Web-i enabled relay controller from anywhere in the world. This means your any device with a browser can access this board anywhere internet access is available. Before you can communicate to a Web-i device globally, port forwarding must be configured on your router.

Port Forwarding

When using this board over the internet and outside the Local Area Network, Port Forwarding will be required. Port Forwarding is a protocol used by your router to allow incoming requests for connections to get through to a specific device on a specific port. Below is an example of how it works. In this example a router has been setup to forward incoming requests for port 2101 to the device at the IP Address 192.168.2.19 on port 2101. Now when any device that tries to access this Port on the External IP Address the router will see the request and automatically forward the request to the device at the IP Address of 192.168.2.19 on port 2101. If this Port Forwarding rule was not in place and a request came in on port 2101 the router would not know which port or device to forward it to and the request for connection would be denied. Note: Port Forwarding will not be necessary when using this within a Local Area Network. For more on Port Forwarding with detailed instructions for every router visit: https://portforward.com/ .

Smart Phone Control

Once the Web-i web page appears on your smart phone, bookmark the page so you can access your relays just like an App on your home screen of your smart phone. Using this method, you can be anywhere in the world and still monitor and control relays as long as your mobile device has an internet connection. It even works using 3G and 4G internet services, so you can be in your car and stay in control of your relays.

Induction Suppression

Perhaps the most overlooked aspect of relay control is proper handling of inductive loads. Inductive loads can best be defined as anything with a magnetic coil, such as a motor, solenoid, or a transformer. Controlling a inductive load using this relay controller requires the use of induction suppression capacitors. The purpose of this capacitor is to absorb the high voltages generated by inductive loads, blocking them from the contacts of the relay. Without this capacitor, the lifespan of the relay will be greatly reduced. Induction can be so severe that it electrically interferes with the microprocessor logic of our controllers, causing relay banks to shut themselves down unexpectedly. In the case of Ethernet devices, customers may experience loss of communications until the device is reconnected. Capacitors that we offer are available at checkout, for more information view our Induction Suppression Video.

Built-In Web Pages

All Web-i boards have built-in web pages that can be accessed through any browser. These pages are not on any internet site they are located in the Ethernet module installed on the board. When you access the IP address of the board with any browser you will see these pages. Below are screen shots of the working pages. Using an FTP program the pages can be transferred from the module to your favorite html editor and modified, your logo or your customer's logo for example and more.

Relay Control Page

This page has buttons for turning relays on and off and also gives you a status of the relay. The descriptions can be easily changed to identify what you are controlling.

Sensor Page

This board is equipped with eight analog to digital sensor inputs that can read a voltage between 0 and 5 volts. The board converts the voltage to a numerical value between 0 and 255. This page displays the numerical value as well as a graph.

Custom Control Page

Custom control with My Page! My Page allows you to create custom buttons and use the full power of the ProXR Command Set. Momentary, toggle and delay commands can be easily configured so one push of the button produces your desired action!

Configuration Page

When security is a concern you can set a password to access the pages through the configuration page. You can also create a name for the board and enter the physical address of the board, handy for users with more than one board.

Network Page

The Network Page contains the IP address of the board as well as the MAC address of the Ethernet module.

Console Page

The Console Page allows users to send ProXR Commands directly to the board. Great feature for bench testing and getting the commands correct for the custom page.

Easy Software Development

Most of our customers write their own program for controlling these devices. Since you can use almost any programming language, you can use one that is most familiar to you so you don't have to learn a new language. These boards support the Serial Port Profile, meaning they will mount to the computer as a virtual com port. This makes it very easy to send commands to the device.

Plug-In for Visual Studio

The NCD Component Library is a plug-in for the Visual Studio 2005/2008 that greatly simplifies the communications to the NCD product line. The samples can be run in Visual Studio and full customization to your needs. Over 40 samples included with this free download! Component Library.

Base Station software supports every feature of this device - no other controller manufacturer even comes close to offering this type of software. Base Station works by communicating with your controller to identify the model and provides the appropriate graphical user interface for setting up and testing the identified device. To help you get started and learn this controller Quick Start Guides are available for just about every feature. As you discover a feature in Base Station a link is provided where you can easily download the Quick Start Guide.

Essential Power Requirements

Applying Good clean power to the board is essential for the operation of the board. Not only for the switching of the relays but the firmware that processes the commands. Without good steady clean power from a regulated power supply the board simply will not function correctly. All boards on the site require 12 VDC power. The PWR12 US power supply is a 120VAC to 12VDC 1.25A 60Hz regulated power supply and it plugs into the barrel connector on the board. The output connector is a 2.1mm I.D. x 5.5mm O.D. x 9.5mm Female R/A barrel connector. We also carry an international power supply with interchangeable adapters for international customers.

Read Analog Sensors

This ProXR controller offers a 8-Channel 8/10-Bit Analog to Digital Converter in addition to relay control. Read and control from 8 sensors per board from 0 to 5 volts!

ProXR Enhanced Firmware Installed

This board has ProXR Firmware installed that responds to the full ProXR Command Set. The ProXR Firmware is the industry leading firmware for controlling relays with more commands and functionality than any other board on the market. The list of commands and parameters this board is capable of is extensive. ProXR Enhanced is the newly released enhance version of the ProXR Firmware with more commands, more functionality and better control than ever before! For a detailed list of all the commands with descriptions see our ProXR Enhanced Command Set.

DPDT Relays Installed

This board has DPDT relays installed. A single DPDT relay is made up of 2 SPDT switches. Each relay acts as two switches that are activated at the same time. This allows two independent signals to be switched at one time. In effect, there are two independent switches on a single DPDT relay - they will always switch together.

There are two connectors with Normally Open, Normally Closed and Common for each relay allowing two separate connections. The picture above shows the 4-channel connectors. The diagram to the right shows the how the arms of the common connector swing from the Normally Closed to the Normally Open positions when energized. Wiring to either the NO or NC can produce your desired results.

2-Million Cycles

ProXR series controllers are designed for long life, you should expect to get years of service from your controller and literally 2-million cycles from the relays on board. With a 5-year warranty and a money back guarantee you have nothing to loose! Place your order now, while everything is in front of you.

RoHS Compliant

This board is led free and RoHS Compliant. If your requirements are for RoHS compliant parts this board is manufactured with RoHS compliant led free parts and solder.

Add Relays as Your Needs Grow

The ProXR series controllers are expandable up to 256 total relays. The controller is fitted with an XR Expansion Port where you can add expansion boards to this relay. Expansion boards can be added until you reach 256 total relays. The Expansion Boards get their logic from the main board and will require 12 VDC power. Expansion boards do not need to be the same relay amperage as the main board or other expansion boards.

16 User-Programmable Timers

The ProXR Series controllers have 16 user-programmable timers. Each independent timer can be assigned to any relay, and can be programmed to hold the relay in the On state, or to pulse the relay at the end of the timer. The ProXR timing features are ideally suited for Watchdog, Keep Alive, and Server Reboot applications, as well as sprinkler systems, gate openers, and lighting applications. Relay Timing Features support two modes of operation: Duration and Pulse. Duration timing is ideally suited where a device should be activated for a period of time. Pulse timing mode is designed specifically for server reboot applications, whereby, if the timer is not reset periodically by your software, the timer will run out and reboot your computer.

5-Year Warranty/Money Back Guarantee

ProXR series controllers are guaranteed against manufacturing and functionality defects for a full 5 years! Not to mention a 30-day money back guarantee! If for any reason you are not happy with a relay purchased from Relay Pros, simply return it within 30 days and we will give you your money back!
